As usual in the package to create a class project, when the class is running, it reported The project:. Test which is referenced by the classpath, does not exist error,
What code is no problem, through online, the original name of the project is the result of repeated cause, but I do not repeat it.
Think may be the previous workspace, there have been the name of the project file, so try a bit of the changed project name, a run just fine.
